Zulip lets you mute topics and channels to avoid receiving notifications for messages
you are not interested in. Muting a channel effectively mutes all topics in
that channel. You can also manually **mute** a topic in an unmuted channel, or
**unmute** a topic in a muted channel.

Muting has the following effects:

* Messages in muted topics do not generate notifications (including [alert
  word](/help/dm-mention-alert-notifications#alert-words) notifications), unless
  you are [mentioned](/help/mention-a-user-or-group).
* Messages in muted topics do not appear in the [**Combined
  feed**](/help/combined-feed) view or the mobile **Inbox** view.
* Muted topics appear in the [**Recent conversations**](/help/recent-conversations)
  view only if the **Include muted** filter is enabled.
* Unread messages in muted topics do not contribute to channel unread counts.
* Muted topics and channels are grayed out in the left sidebar of the desktop/web
  app, and in the mobile app.
* In the desktop/web app, muted topics are sorted to the bottom of their
  channel, and muted channels appear in a collapsible section at the bottom of
  their channel folder in the left sidebar.

You can search muted messages using the `is:muted` [search
filter](/help/search-for-messages#search-by-message-status), or exclude them
from search results with `-is:muted`.

  **Note**: Some parts of the Zulip experience may start to degrade
  if you receive more than a few hundred muted messages a day.
